PURPOSE: To insulating-coat the whole circumference and
improve liquid leakage proofness by inserting the unwoven cloth
tape which is immersed in hot-melt insulant into the exposure
section caused by removal of a compression jig after the insulating
coat is formed.

CONSTITUTION: The compression jigs 11 and 12 are contacted
on both the center of the upper end positive electrode terminal block
9 and that of the lower end carbon film 2 in the laminated body 7 on
which a number of flat cells are properly laminated and are
compressed into fixed dimensions. Then these are immersed into
the fused liquid 14 of hot-melt insulant such as fused polyamide
system hot melt adhesive, wax, and paraffin and the coated later 15
is formed. Subsequently, the unwoven cloth tape 18 which is
perforated in the same shape as the exposure section 16 and in
which polyamide system hot melt adhesives are immersed is
inserted into the exposure section 16 caused by removing the
compression jigs 1 1 and 12. The heating pressing jigs 20 and 20'
are contacted, heat climped, and immersed, and the whole
circumference is sealed with insulant.
